基于数学形态学的混合消噪法

工程图纸的矢量化过程中,噪声的正确消除一直是比较难解决的问题.为了提高图纸消噪的效果,在研究了噪声消除方法、图纸噪声特点与消噪要求以及形态学在图纸噪声消除方面的应用后,提出了一种改进的消噪法:混合消噪法,以形态学的膨胀与腐蚀基本运算为基础,通过加减运算、开闭运算的多次混合,达到了既消除图纸噪声,又不丢失细线条目标的目的,对工程图纸的处理有较大的应用价值.

Hybrid method in noise removing based on mathematical morphology

In the process of getting vector drawing, how to remove the noises is always difficulty, In order to improve the result of in noise removing of drawing, a new method in removing of noises, which is hybrid method in removing of noises, is put forward alter studying the method in removing of noises, the character and needing of drawing in removing of noises and the application of morphology in noise removing of drawing, which is based on the operation of expantion and erosion, by the multi-mix operation of plus-minus and open-close operation, on the one hand the noise of drawing is removed, on the other hand the thin line of drawing is preserved, -this method benefit the processing of the drawing.
